Wehrli Custom Fabrication Gloss White High Flow Intake Bundle Kit for 2017-2019 Chevy/GMC (L5P Duramax)

Fits select 2017-2019 Chevrolet Silverado and GMC Sierra 2500 HD / 3500 HD models equipped with the 6.6L L5P Duramax diesel engine.

The WCFab High Flow Intake Bundle Kit is a Stage 1 upgrade designed to resolve factory airflow restrictions and eliminate failure-prone plastic components. This kit replaces the factory 2.5-inch diameter hot side intercooler pipe and the two-piece plastic/rubber cold side assembly with heavy-duty, one-piece mandrel-bent aluminum piping. By increasing the hot side to 3 inches and the cold side to 3.5 inches, this bundle improves turbo spool-up, throttle response, and overall engine efficiency.

Constructed in the USA from 14-gauge aluminum, these pipes feature a durable Gloss White powder coat finish. The hot side pipe eliminates the OEM resonator for better flow, while the cold side pipe utilizes a CNC-machined flange with a double O-ring seal to prevent the boost leaks common with the factory clip-ring design. This system is a direct bolt-on replacement that requires no aftermarket tuning.
